Data organization.

Data have been organized into two groups by year; 
files are prefixed by CR05 and CR05.

Each datafile contains a matrix of data for one variable:
P,T,C,S,SIGMA,U,V 

Each row represents a single vertical profile, with depth increasing
along each row; the depth is nominally at 1-m intervals, but the
actual mean pressure is given in the P file.  The time, location, and
bottom depth are given by lat,lon,time and hmax files.  NaNs represent 
regions with no data. 

The following files have been generated:
